What is a smart AI assistant?
A smart AI assistant answers questions from your visitors based on your own website and documents, and hands the conversation over to a team member when needed.
How does the ZelixAI chatbot work?
A virtual employee that answers questions 24 hours a day — based on your own knowledge, not on random information from the internet.
The ZelixAI chatbot is much more than a chat widget with canned replies. It is a fully-fledged digital colleague powered by large language models, supplemented with a technique called retrieval-augmented generation. In practice that means: the moment a visitor asks a question, the bot first searches your own knowledge base for relevant information and only then formulates an answer, grounded in what it actually found.
The result is a chatbot that does not hallucinate. It doesn't invent prices, doesn't make up opening hours and doesn't guess at warranty terms. Everything it says can be traced directly to a source in your own documentation. If it doesn't know something, it says so and hands the conversation off to a human colleague — complete with the full chat history, so your employee doesn't have to start from scratch.
The bot can be placed on your website within minutes. A single line of HTML in the footer and the widget appears on every page. Styling it to match your brand (colours, typography, name, avatar) happens through a visual interface — no coding skills required.
Training: how the AI learns your business
Within an hour your AI chatbot goes from a blank canvas to a knowledgeable conversation partner. No data scientists required.
The ZelixAI training process is deliberately simple. You don't need a machine learning expert on staff and there is no expensive data science project involved. All you do is supply your own content — in whichever format is easiest for you.
Sources you can connect
- Knowledge base articles — added manually through our editor.
- Documents — drag PDFs, Word files, manuals and whitepapers straight into the upload zone. The AI automatically parses the text, tables and headings.
- Website crawler — provide your domain and the crawler walks through your public pages, extracts the relevant text and adds it to the knowledge base. You can exclude specific URL patterns.
- Q&A pairs — for frequently asked questions where you want to guarantee the exact answer, simply add a question-and-answer pair. These take priority over generated responses.
Once your content is supplied, it is automatically split into small pieces (chunks) and turned into mathematical vectors that represent the meaning of the text. This process is called embedding. These vectors are stored in a specialised database that can search by meaning rather than just keywords at lightning speed — a question about "rates" automatically matches articles that talk about "prices" or "costs" as well.
The first version of your bot is usually live within an hour. From that moment on you can test, provide feedback and fine-tune immediately.
Continuous learning: the bot gets better every week
A chatbot that only ever answers with what you loaded into it once will quickly fall behind. That is why ZelixAI keeps learning every single day — with no manual retraining required.
The learning process works on three levels. First, the system analyses every conversation and tracks which questions the bot could answer with confidence and which it couldn't. As soon as a particular question recurs and the bot responds uncertainly, you receive a notification in the dashboard: "this topic is missing from your knowledge base". One click later you can add a new article or Q&A pair.
Second, the system tracks the quality of answers. Every customer can rate a conversation with a thumbs up or thumbs down, and your employees can leave internal notes on conversations that could have gone better. This feedback is processed automatically: conversations with negative feedback are flagged for review, and recurring patterns become visible in analytics.
Third, the AI detects knowledge drift. When you update a knowledge base article, all related embeddings are automatically regenerated. When you delete an article, the knowledge instantly disappears from the bot. There is no risk of the bot continuing to push outdated or contradictory information.
For organisations that want even more control, there is a bot-testing environment where you can validate new answers before they go live. You can define a set of representative questions, have them run automatically after every change to the knowledge base and compare the answers to previous versions. That way you know for sure that an update actually improves the bot rather than making it worse.
Ten industries, one platform
Don't think of it as a generic answer robot, but as an employee who is specialised in your sector. You can use it for wildly different purposes.
The interactive demo above shows ten typical use cases. Every industry has its own questions, its own terminology and its own sensitivities — and the bot adapts accordingly:
Opening hours, allergens, custom orders and reservations — typical questions that are time-consuming to answer manually.
Delivery times, return procedures, payment methods and track-and-trace. Integrates with your order system for real-time information.
Password resets, VPN issues, printer problems and first-line triage. Automatically creates tickets for complex cases.
Scheduling viewings, looking up rental prices, explaining bidding procedures and submitting documents.
Triage for acute complaints, repeat prescriptions, insurance coverage and appointments.
MOT scheduling, service quotes, courtesy car requests and status updates on ongoing repairs.
Initial intake, scheduling introductory meetings, hourly rates and legal aid questions.
Membership information, class schedules, sign-ups and cancellation procedures — available 24/7.
VAT deadlines, rates per service, payroll administration and answering client questions between audits.
Reservations, menu questions, dietary requirements and catering requests. Speaks multiple languages for international guests.
These are of course just examples. The bot works in virtually any sector where customer questions recur. The real power doesn't sit in an industry template — we deliberately avoid those — but in the AI's ability to understand your own knowledge and reproduce it in your own tone of voice.
The technology under the hood
AI infrastructure with the simplicity of a plug-and-play SaaS solution.
ZelixAI works with several language models and chooses the one that fits each question. For most customers the default setting is more than enough and strikes a good balance between quality and cost. Want more say over where your conversations are processed? You decide that in your privacy settings.
All data is stored on our own servers in a Dutch data centre. Communication happens exclusively over TLS 1.3, API keys are encrypted at rest with AES-256 and access to your dashboard is protected by mandatory 2FA for every administrator. Every action in the system is recorded in an immutable audit trail.
Integrating with existing systems happens through our REST API and webhooks.
